Worked

This issue was fixed in 2.2.0-beta3 version of PSReadLine. You can fix this by upgrading to the latest 2.2.0-beta4 version of PSReadLine. Instructions for doing so:

1. stop all instances of pwsh.
2. from cmd.exe run: pwsh -noprofile -command "Install-Module PSReadLine -AllowPrerelease -Force"

---

If you want to remove that beta version of PSReadLine and use the 2.1.0 version of PSReadLine that's shipped with PowerShell 7.2, you can:

1. run pwsh -noprofile -noninteractive to start pwsh without loading PSReadLine
2. run Uninstall-Module -Name PSReadLine -RequiredVersion <2.2.0-beta1 or 2.2.0-beta2> -AllowPrerelease to remove the module. Or, you can manually remove that module folder.
